Overview of Migrating User State and Settings in Windows 8.1

          A user state migration captures all of the custom settings on a group of existing computers, known as source computers, and restores these settings on a group of newly deployed computers, known as destination computers. Typically, you would perform a user state migration during or after the deployment of a new operating system. A user state migration enables users to be more productive because they do not have to spend time reconfiguring settings or looking for personal
data after a deployment.
